L-Glutamine plays an important role in many bodily functions such as protein synthesis, brain function, intestinal health, blood sugar, and energy levels. It converts more quickly into glucose than other amino acids and therefore helps maintain healthy blood sugar levels.

Because it can pass the blood-brain barrier, it is known as brain fuel. In the brain it is converted to glutamic acid which is essential for cerebral function. Glutamine is found in large amounts in the muscles and is readily available when needed for the synthesis of skeletal muscle proteins. Because this amino acid helps build and maintain muscle, supplemental glutamine is useful for dieters and persons doing strength-training exercises.

Contraindications:
Do not take if allergic to MSG (monsodium glutamate), L-glutamine may cause excess excitation and reaction.

Drug Interactions:
None known

Can this product be taken in a hot liquid such as tea or soup? Glutamine can be taken with a slightly warm liquid but not with a hot liquid since one then risks decomposition of the product.

Are the capsules made from beef? Yes, the capsules used in this product are made from beef.

Is L-Glutamine safe to take if I have an intolerance for MSG (monsodium glutamate)? Glutamine is related to the amino acid glutamic acid (or glutamate, found in most protein foods) and may influence body levels, but typically follows a slightly different route of metabolism. However, people who are sensitive to the excitatory effects of the amino acid glutamic acid (glutamate or msg) may experience excess excitation and react to glutamine, in which case do not take this product.

I have been training for a half marathon over the past few months and I read L-Glutamine could help with strength as well as muscle recovery. After long runs my knees and hips would have mild levels of pain and soreness which often result from long runs of course. But
after I started using L-Glutamine my recovery is within 1 day. It wasn't odd for me to take 3 days to fully recover from a 10 mile run, so needless to say I am very pleased with this product. Thank you ProHealth! ...[read entire review]
